  /* Purpose: Stretch second variable to match dimensions of first variable
     Dimensions in var which are not in wgt will be present in wgt_out, with values
     replicated from existing dimensions in wgt.
     By default, wgt's dimensions must be subset of var's dimensions (MUST_CONFORM=true)
     Calling routine should set MUST_CONFORM=false if wgt and var need not conform
     When wgt and var do not conform then then nco_var_cnf_dmn sets *DO_CONFORM=False and returns copy of var with all values set to 1.0
     Calling procedure then decides what to do with unity output
     MUST_CONFORM is True for ncbo: Variables of like name to be, e.g., differenced, must conform
     MUST_CONFORM is False false for ncap, ncflint, ncwa: Some variables to be averaged may not conform to specified weight, e.g., lon will not conform to gw. This is fine and returned wgt_out may be discarded. */

  /* There are many inelegant ways to accomplish this (without using C++): */  

  /* Perhaps most efficient method in general case is to expand weight array until
     it is same size as variable array, and then multiply these arrays together 
     element-by-element in highly vectorized loop (possibly in Fortran or BLAS). 
     To enhance speed, (enlarged) weight-values array could be static, only re-made
     when dimensions of incoming variables change. */

  /* Another general method, though more expensive, is to use C to figure out the 
     multidimensional indices into the one dimensional hyperslab, a la ncks. 
     Knowing these indices, routine could loop over the one-dimensional array
     element by element, choosing the appropriate index into the weight array from 
     those same multidimensional indices. 
     This method can also create a static weight-value array that is only destroyed 
     when an incoming variable changes dimensions from the previous variable. */

  /* Another method, which is not completely general, but which may be good enough for
     governement work, is to create Fortran subroutines which expect variables of 
     a given number of dimensions as input. 
     Creating these functions for up to five dimensions would satisfy most situations
     C code would determine which branch to call based on number of dimensions
     C++ or Fortran9x overloading could construct this interface more elegantly */

  /* An (untested) simplification to some of these methods is to copy the 1-D array
     value pointer of variable and cast it to an N-D array pointer
     Then C could handle indexing
